Vertical projectile motion

Describe the motion resulting from the velocity vs time graph shown below, assuming an initial height of 0 m, and draw a displacement vs time graph and an acceleration vs time graph:

Chipa Thomas Maimela‘s insight:

The object starts with an initial height of 0 m, moves upwards for 1 s, then slows and falls back to its starting position where it bounces upwards at a higher velocity, and travels upwards (higher than before) for 2 s, then stops and falls back to its starting position where it bounces upwards again at an even higher velocity, travelling over 3 s to an even higher position, before finally falling back to the ground and stopping.
